Looks to me as if now they plan to blame it on Rasinksi, the trooper who was driving. Here’s an extract from the article you just linked:
The driver has discretion over the traveling speed and when to activate emergency lights, Fuentes said. He said the investigation showed that the governor did not ask Rasinski to speed up.
In non-emergencies, the governor’s drivers should obey the traffic laws “in the interest of safety both to the occupants of their car and the public,” Fuentes said.
Rasinski, who has been part of the state police executive protection unit for a year and is in his eighth year as a trooper, had two prior accidents on the job. One accident, in which he slid on an icy road and hit a guard rail, was deemed preventable, according to New Jersey State Police Capt. Al Della Fave.
